To (r/Z whom t may concern.-

Be it known that I, CARL FRIEDRICH PHIL- IPP STENDEBACH, a subject ofthe King of Saxony, and a resident of Leipsic, Kingdom of Saxony,Germany, have in vented certain new and useful Improvements in ElectricFeed Devices for Motor-Cars, of which the following is a full, clear,and exact description.

The present invention consists of improvements in electric feed devicesfor motor-cars driven by electricity. 'lheinvention consists moreparticularly in a device for making and breaking the current between thefeed-line and the contact-heads of the'sectional conductors each timethe car passes over the line.

In order to render the present specification more easilyintelligible,reference-is had to the accompanying drawings, in whichsimilar letters of reference denote si milar pari s throughout theseveral views.

Figure 1 is a cross-section through one of the devices and through thechannel under the rail, in which the plow runs; Fig. 2, a side elevationof a part of the line, showing the channel in longitudinal section',Fig. 3, a plan of the device with the channel in section; Fig. 4, asectional side elevation showing the roll which is operated by the plow,and Fig. 5 a detail view of the cover of the housing, seen fromunderneath and drawn to a larger scale.

The device consists ot' a box 1, having an upper cylindrical part and alower rectangular part and having a channel-like part, to In thischannel the plow of the car, having the knife-like edge 19, runs andpassing between the rolls 5 and the stationary roll Sa pushes the formerroll 5 inwardly against the action of its spring 6. rIhe roll 5 ismounted in the bifurcated end 4 of a bar 4, adapted to slide in a guidein the housing 1. The interior end of the said bar 4 is formed to arack, which engages a ring of teeth 3, formed around the cup-shapedlower end of the vertical spindle 3. The latter is made in two partscoupled together by a square end on the one part sliding in acorresponding socket of the other, or the said `end may be of apolygonal section and the socket accordingly shaped. The spindle isguided or supported at its lower-end in au inner chamber of the housing1 and at its upper end in the cover 2 of the said housing. The chamberis tightly closed by a cover and a' joint-ring 1S, of elastic material,and has a down wardly-extending covercylinder, which encircles the shaftor spindle 3 and dips into the cup at the bottom ot' the latter. Thiscup is filled with quicksilverand completely closes the chamber againstdust and dampness. Above the cover is au insulated disk 15, ofinsulating material, which is provided with two contact-points 13 and14, and above this again, fast on the spindle 3, is a rotary disk, ofinsulating material, 9, having formed therein the contact-points 10 and11, which may be connected together by a conductor 12, embedded in thesaid disk, as shown at Fig. 1. The contacts 10 and 11 and 13 and 14 areso arranged that when the disk 9 is turned they will make the circuitfrom the feed-conductor 16, with which 14 is in connection'through 11,10, and 13, which latter is in connection with the sectional conductorleading to the contact-head for the car-feed. The spring 6 operates toreturn the parts to their initial positions after the device has beenoperated by the plow, and its action may be supported and increased bymeans of a flat spiral spring 21, mounted on the cover 2, and which actsto turn the disk 9 back when the plow has released the roll 5. The disk9 is provided with an upwardly-extending pin 20, which is attached tothe free end of the spring 21, said pin extending upwardly through aslot 20 of the cover-flange, as will be seen from Fig. 5. Thecounter-roll 8 is mounted in a fork 8, fast in the channel-wall. Insteadof the rack and pinion, any other device might be emin, insulatedcontacts, one connected with the4 feed-line and one with the sectionalconductor, a rotary disk fast on said spindle and IOO having contacts tocontact with said stationary .contacts when the disk is turned, ahorizontally-extending roll projecting into the plow-channel and meansin connection with a roll-supporting bar to turn the said spindle whenthe said roll is acted on by the plow substantially as described.

2. The combination of a housing having mounted therein a verticalspindle, contacts to rotate with said spindle, stationary contacts tocontact with said rotary contacts when the spindle is turned and makecontact from the feed-line to the sectional-line contact-heads, ahorizontal slide guided in the said housing and extending into theplowchannel and means in connection with said slide to turn the saidspindle when the plow pushes it inwardly and means for returning thespindle to its initial position when released substantially asdescribed.

The combination of a housing having an inner chamber a vertical spindlemounted therein and having a Quicksilver-cup at its lower end, a coverto said inner chamber having a downwardly-extending sleeve to dip into fsaid cup said sleeve inclosing the said spindle, rotary contacts fast onsaid spindle and stationary contacts connected up as specified tocontact with said rotary contacts when the spindle is turned, ahorizontally-guided slidebar to extend out of the said chamber into theplow-channel in the path of the plow and means in connection with saidslide to rotate the said spindle when the slide is moved by the plow andmeans for returning the parts to their initial position substantially asdescribed.

4. The combination of a housing having mounted therein a verticalspindle, contacts fast to said spindle and stationary contacts connectedup as specified, to contact with said spindle-contacts when the spindleis turned, a slide-bar to slide horizontally said bar being mounted inthe housing-wall and extending into the path of the plow, a rack at theend of said bar and a ring of teeth on the end of the said spindle withwhich said rack engages and means for returning the parts totheirinitial position when the plow has released or passed the end ofthe said slide substantially as described.

5. The combination of a housing having aninnerchamberandavertically-mounted spindle therein made in two parts, acontact-disk on the upper spindle part and contacts to contact withstationary contacts mounted as specified and connected up in the mannerdescribed, a Quicksilver-cup formed at the lower end'of the saidspindle, a cover to the chamber having sleeve encircling the saidspindle and dipping into the Quicksilver-cup, means for coupling the twospindle parts, a horizontally-sliding bar extending out of the chamberinto the plow-channel in the path of the plow and means for rotatingsaid spindle when the bar is moved by the plow and for returning theparts to their initial position substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
